Abstract:In order to improve the shape quality and reduce the roll loss, a comprehensive judgment index of roll loss is proposed, which can judge the degree of roll loss from the lubrication process system. Then, combined with the equipment and process characteristics of the cold continuous rolling unit, a set of work suitable for the control of roll loss is established The comprehensive optimization technology of lubrication system can minimize the pressure between the rolls of each stand without affecting the shape quality. Meanwhile, it can ensure that the unit will not slip and hot sliding damage, and reduce roll consumption. It has been applied to the production practice of cold continuous rolling mill, which has achieved good results, good comprehensive economic benefits, improved market competitiveness and further promoted wide value.
